Division I College Wrestling RPI & ISR Ratings

Submitted by Britt Malinsky
January 29, 2007

Note: The first is the RPI, with its 25-50-25 base formula, and no adjustments have been made. The second is the ISR, which is described by its creator, Boyd Nation, like this:

RPI: 25% winning percentage, 50% opponents' winning percentage, 25% opponents' opponents' winning percentage. It's the same formula the NCAA created for men's basketball, among other sports, as a guide for who to select and how to seed teams for the NCAA Tournament

ISR: "The basic idea is an iterative one. Begin with all teams set to an even rating -- 100 in this case. Then, for each game played, give each team the value of their opponent's rating plus or minus a factor for winning or losing the game -- 25 in this case. Total all of a team's results, divide by the number of games played, and that's the end of a cycle. Then use those numbers as the start of the next cycle until you get the same results for each team for two consecutive cycles."

NOTE: This is just for DUAL MEETS, not Tournaments
